part of NASCAR's rules update for the 2023 season includes penalties for any one trying to use Ross Chastain's Moose Fraternity Chevrolet technique of full power wall sliding around the track, last October.

In future, NASCAR officials will issue time penalties to "any vehicle that attempts an unsafe maneuver like Chastain's". Such passes will thus be fruitless in future, as any positions gained by such a maneuver will be duly lost. "We will penalize for that act going forward," said Elton Sawyer, NASCAR’s senior vice president of competition. "Basically, what it would be is a lap or time penalty at the end of the race, so that move at Martinsville would be a penalty."

Chastain's pass at Martinsville saw him ride his car along the wall at full throttle, gaining five positions in the final dash to the line. The pass was a Hail Mary—a last-ditch attempt at staying in contention for the championship.

Chastain, the most amazing guy to happen to Nascar, fucking legend, and I bet he needs a sling to keep the brass balls from smashing his knees when he walks.
